How do we know that God gathers His people despite rejection?

The concept of God's gathering of His people amidst rejection is clearly depicted in Matthew 23:37, where Jesus expresses His longing to gather His children. This gathering is an active work of grace, initiated by God through the proclamation of the gospel. Even in the face of resistance, like the opposition faced by the prophets, God still sends His messengers to call His chosen ones out of darkness into His marvelous light. The gospel serves as the means by which God reaches the hearts of His people, demonstrating His relentless pursuit of them, regardless of their initial rejection.
